Alcott House in Ham, Surrey, was the home of a utopian spiritual community and progressive school which lasted from 1838 to 1848. Supporters of Alcott House, or the Concordium, were a key group involved in the formation of the Vegetarian Society in 1847.

Ham is a suburban district in Richmond, south-west London. It has meadows adjoining the River Thames where the Thames Path National Trail also runs. Most of Ham is in the London Borough of Richmond upon Thames and, chiefly, within the ward of Ham, Petersham and Richmond Riverside; the rest is in the Royal Borough of Kingston upon Thames. The district has modest convenience shops and amenities, including a petrol station and several pubs, but its commerce is subsidiary to the nearby regional-level economic centre of Kingston upon Thames.
